General Information Yttrium: Y Atomic Number: 39 Atomic Mass: 88.9059 Number of Protons: 39 Number of Electrons: 39 Most Common Isotope: -1 Number of Neutrons in most common Isotope: 50
Missing Bohr model -1 Background Scientist who discovered Yttrium: Anders Ekeberg Year discovered: 1797 Origin of name: Carl Arrhenius discovered Yttrium in a black compound which he named Ytterbyte after Ytterby Bengt Geijer after a miner. Johan Gandolin received a sample of Ytterbyte and did a detailed analysis and found 31% silica, 19% alumina, 12% iron oxide and 38% of an unknown earth. Anders Ekeberg confirmed his findings and suggested the name Yttria for the metal’s oxide so it was named Yttrium. Chemical Family: Transition Metal Common Uses: Yttrium is often used to strengthen alloys such as aluminum. Yttrium-90 a radioactive chemical is used to attack cancers and is used to sever pain causing nerves in the spine.
Physical Properties State of matter at room temperature: Solid Melting Point: 1525 C Boiling Point: 3340 C Density: 4.47 g/cm3 Abundance in earth’s crust: 33 parts per million by weight Chemical Properties Element that will react with Yttrium: powdered it will react with oxygen in air at high temperatures, Two compounds that contain Yttrium: Found in Uranium ores and almost all rare earth minerals
Important Use
Yttrium oxide, one of the most important compounds of Yttrium, is used to make the high-temperature superconductor YBCO (yttrium barium copper oxide). This becomes superconducting at -178 C which means that is can be kept as a superconductor while using liquid nitrogen instead of a more dangerous liquid; helium.
